Industrial reverse osmosis
Industrial RO plants, designed for your water
Reverse osmosis pushes water through membranes fine enough to hold back dissolved salts, bacteria and most impurities. We design RO plants around your raw water and the purity you need.
Overview
What it is
An RO plant uses high pressure to force water through semi-permeable membranes. Pure water passes through; dissolved salts and contaminants stay behind and leave as a concentrated reject stream.
The membranes do the work, but what makes a plant last is everything around them: the pre-treatment that protects the membranes, the right pump and membrane sizing, and dosing that stops scale. We design all of it from your water analysis.
The treatment train
Inside an RO plant
Pre-treatment
Multi-media and carbon filters, with softening or antiscalant dosing, remove the solids, chlorine and hardness that would damage the membranes.
Micron filtration
Cartridge filters catch the fine particles that get past pre-treatment.
Reverse osmosis
A high-pressure pump drives water through the membranes, separating pure permeate from concentrated reject.
Post-treatment
pH correction, UV or remineralisation, depending on what the water is for.

Questions
What buyers ask us
How much water does an RO plant reject?
It depends on your raw water and the plant's recovery rate. The reject can often be reused for non-critical uses. The proposal gives the expected recovery for your water.
How long do RO membranes last?
With good pre-treatment and regular cleaning, membranes last for years. Poor pre-treatment is the most common reason they fail early.
What size of RO plant do I need?
Size comes from how much treated water you need per hour or per day, with margin for peaks and cleaning. Tell us your demand and we'll size it.
Need an RO plant?
Send us your water analysis and how much water you need each day, and we'll size a plant for you.
